A nurse is caring for a client who is receiving oxygen at 2 L/min via a nasal cannula. The nurse recognizes the client is receiving which of the following inspired oxygen concentration?

A) Bright light: Exposure to bright light, especially in the evening or at night, can interfere with the body's production of melatonin, a hormone that regulates the sleep-wake cycle. Bright light exposure can disrupt circadian rhythms, making it more challenging to fall asleep and stay asleep.

B) Drinking caffeinated beverages in the evening: Caffeine is a stimulant that can interfere with sleep by blocking the effects of adenosine, a neurotransmitter that promotes sleepiness. Consuming caffeinated beverages in the evening can delay the onset of sleep and reduce overall sleep duration.

C) A 20-minute nap during the day: While short naps can be beneficial for some individuals, especially if they are sleep-deprived, napping for too long or too late in the day can disrupt the body's natural sleep-wake cycle. Short naps can be refreshing, but longer or late-day naps can make it harder to fall asleep at night.

D) Emotional stress: Stress and anxiety can trigger the body's "fight or flight" response, leading to increased alertness and difficulty relaxing or falling asleep. Chronic stress can disrupt the sleep-wake cycle, leading to difficulty initiating or maintaining sleep and resulting in poor sleep quality.

E) A regular bedtime schedule: Having a consistent bedtime schedule can actually help regulate the sleep-wake cycle by reinforcing the body's internal clock. Going to bed and waking up at the same time each day, even on weekends, can help improve sleep quality and make it easier to fall asleep and wake up naturally.

Answer: C. "I should expect the hospice team to help me manage my dyes."

A. "I will have to be admitted to a long-term care facility in order to receive hospice care."
This statement reflects a misunderstanding of hospice care. Hospice services can be provided in various settings, including the client’s home, hospice centers, or even long-term care facilities, but clients are not required to be admitted to a long-term care facility specifically to receive hospice care.

B. "My oncologist will continue to look for a cure for my cancer while I am receiving hospice care."
Hospice care focuses on comfort and quality of life for clients with terminal illnesses, rather than curative treatment. Clients receiving hospice care have typically decided to forego curative treatment to prioritize symptom management and palliative care.

C. "I should expect the hospice team to help me manage my dyes."
This statement indicates an understanding of hospice care. The hospice team provides comprehensive support to manage symptoms, such as pain and discomfort, as well as addressing emotional, spiritual, and psychosocial needs. The goal is to ensure the client’s comfort during the end of life.

D. "Hospice care services are available to patients who are terminally ill regardless of their life expectancy."
This is not entirely accurate. Hospice care is typically available to individuals who have a life expectancy of six months or less, as determined by their healthcare provider. Therefore, life expectancy is an important criterion for hospice eligibility.
